A donor kidney has been transported to surgeons at a US hospital via drone, in the first trip of its kind.
Many see huge opportunity for unmanned aircraft systems (UAS) transporting medical products, with some drones already doing so in Africa.
The US flight required a specially-designed drone which was able to uphold and monitor the organ.
It is hoped that it can pave the way for lengthier flights and report safety issue with current transport methods.
The three-mile journey requisite a lot of new technology, including a custom-made drone proficient of carrying the additional weight of an organ, which also needed on-board cameras and organ tracking, and communications and safety systems for a flight over an urban, occupied areas.
It also had a parachute retrieval system in case the aircraft botched.
